Economic analysis of biogas application as energy source for electricity power generation is needed to motivate the user candidates (cow farmers) and influence government policy with final goal larger implementation system many purpose reducing fossil fuels sources consumption. The economic 2 kW done by determining equipment installation raw material operational needed, data organic fertilizer prices do calculating profit loss, cash flow, parameters, i.e. Net Present Value (NPV), Internal...
In Indonesia, smallholders have historically practiced agroforestry, which warrants examination in terms of food and livelihood security within sustainable community forest frameworks. Based on a literature review, we analyzed these two forms related to smallholder agroforestry practices. Findings indicate diverse systems, with 88% focusing non-timber products (NTFPs) 12% timber. While 42% prioritize direct supply, 58% emphasize income generation through product sales. However, that does not...
Biogas is a renewable energy derived from the degradation of organic materials, such as agricultural waste, livestock and others. Several Qur'anic verses in Islam explicitly support wise effective utilization natural resources; this includes concept sustainability sustainable management resources. “Eat [therefrom] pasture your livestock. Indeed, that are signs for those intelligence.” an example biogas management' relationship with Qur'an (QS. Thaha: 54). made manure resource line Islamic...
Abstract Anaerobic digestion plays an important role in the gastrointestinal tract and organic waste treatment. Thermodynamic analysis based on reaction Gibbs free energy can be used to predict favorability of some reactions occurring during anaerobic digestion. In this study, we a thermodynamic approach evaluating stoichiometric coefficients process vitro rumen microbiota. The glucose, butyrate, propionate, hydrogen utilizations was analyzed by calculating change each reaction. A previously...
Biogas resulted from anaerobic digestion of organic compounds have various methane content depend on the type degraded material. The biogas is range between 40–80% that influence heating value and combustion characteristic biogas. higher can be obtained through upgrading by removing CO2 other trace components like H2S, NH3, water vapor. This research was a simulation product composition temperature in air equivalence ratio. done chamber at constant pressure 1 atm. enter into approximately 30...
The existence of free molecular oxygen in the biogas production process will inhibit strict anaerobic methanogenic bacteria. estimation O2 concentration slurry is needed to see if inhibition happens without removal initial process. calculation begin with determine digester volume, gas space volume fraction digester, and operation condition, i.e. temperature pressure according good condition Based on liquid-gas equilibrium principle, assumption that air consist 80% nitrogen 20% oxygen, it...
Biogas production from soybean curd industry waste water was studied in laboratory scale to improve the application of anaerobic digestion process. The problem with fact that it does not sufficiently contain microorganisms required biogas production. Therefore, is necessary add a well-developed population accelerate start-up anerobic digestion. This research aimed verify influence addition active digester effluent into batches an Batch experiments were done two digesters. first only fed...
Research on the effectiveness of PAC coagulants for processing tannery waste was carried out to determine optimum pH and % in reducing BOD, COD, chromium, TSS, sulfide, ammonia leather waste. The test jar method is with a beaker filled 300 mL liquid each. A series experiments using flocculator variations, namely 4, 5, 6, 7, 8, 9 fast stirring at 100 rpm 2 minutes, slow 25 15 minutes. Dose variations were doses ppm, 50 75 125 ppm. Determination done by measuring final turbidity value. value...
Disposable diapers have become an overwhelming component of municipal waste streams, exemplified by Bandung's staggering daily influx approximately 1,451,024 into landfills in 2021. Hydrothermal carbonization (HTC) emerges as a potential solution for the valorization this problematic waste, transforming it hydrochar, key ingredient environmentally-conscious briquettes. However, HTC's reliance on substantial water resources underscores urgent need efficiency strategies. This study...
Study concerning the digester unit of biogas power system at Baiturrahman Boarding School is highly needed to understand performance and function each in producing biogas. There are six digesters, named as Digester 1, 2, 3, 4, 5, 6. However, 2 which was purposed for food waste feed has not been operated. The fifth functioning digesters operated with cow manure human faeces raw materials. This research conducted by analyzing process parameters, i.e., TS concentration, VFA slurry pH thickness,...
